书写darBean
先看官网的序列化列子
flutter序列化官网
pubspec.yaml 添加依赖
dependencies:
# Your other regular dependencies here
json_annotation: ^2.0.0
dev_dependencies:
# Your other dev_dependencies here
build_runner: ^1.0.0
json_serializable: ^2.0.0
模仿列子写 darBean
import 'package:json_annotation/json_annotation.dart';
part 'ServerBusiness.g.dart';
//服务项目 （商家bean）
//知道通用否
@JsonSerializable()
class ServerSusiness{
List <ServerGenBean>servegeneralist;
List <ServerPageBean>serverPackageList;
ServerSusiness(this.servegeneralist,this.serverPackageList);
// factory ServerSusiness.fromJson(Map<String,dynamic> json)=>_$ServerSusiness.fromJson(json);
factory ServerSusiness.fromJson(Map<String,dynamic> json)=>_$ServerSusinessFromJson(json);
Map<String,dynamic> toJson()=>_$ServerSusinessToJson(this);
}
@JsonSerializable()
class ServerPageBean {
double serverPackageAmount;
String serverpackagename;
List<SerpageBean_bean> list;
ServerPageBean(this.serverPackageAmount,this.serverpackagename,this.list);
// factory ServerPageBean.fromJson(Map<String,dynamic> json)=>_ServerPageBeanFromJson(json);
factory ServerPageBean.fromJson(Map<String,dynamic> json)=>_$ServerPageBeanFromJson(json);
Map<String,dynamic> toJson()=>_$ServerPageBeanToJson(this);
}
@JsonSerializable()
class SerpageBean_bean {
String intid;
String serveritemname ;
SerpageBean_bean(this.intid,this.serveritemname);
factory SerpageBean_bean.fromJson(Map<String,dynamic> json)=>_$SerpageBean_beanFromJson(json);
Map<String,dynamic> toJson()=>_$SerpageBean_beanToJson(this);
}
@JsonSerializable()
class ServerGenBean {
String fwdlname;
List<Servergean_bean_bean>list;
ServerGenBean(this.fwdlname,this.list);
factory ServerGenBean.fromJson(Map<String,dynamic> json)=>_$ServerGenBeanFromJson(json);
Map<String,dynamic> toJson()=>_$ServerGenBeanToJson(this);
}
@JsonSerializable()
class Servergean_bean_bean{
String fwxlid;
String fwxlname;
double price; //拿到数据是什么类型这里就定义什么样的类型
Servergean_bean_bean(this.fwxlid,this.fwxlname,this.price);
factory Servergean_bean_bean.fromJson(Map<String,dynamic> json)=>_$Servergean_bean_beanFromJson(json);
Map<String,dynamic> toJson()=>_$Servergean_bean_beanToJson(this);
}
注意事项
上面还是要模仿 官网的列子
1、导包
import 'package:json_annotation/json_annotation.dart';
part 'ServerBusiness.g.dart'; //这个是执行命令生成的，我们要写上
2、我们格式化一下 我们的json字符串看一下结构
主Bean
class ServerSusiness{
List <ServerGenBean>servegeneralist;
List <ServerPageBean>serverPackageList;
ServerSusiness(this.servegeneralist,this.serverPackageList);
// factory ServerSusiness.fromJson(Map<String,dynamic> json)=>_$ServerSusiness.fromJson(json);
factory ServerSusiness.fromJson(Map<String,dynamic> json)=>_$ServerSusinessFromJson(json);
Map<String,dynamic> toJson()=>_$ServerSusinessToJson(this);
}
两个次Bean
@JsonSerializable()
class ServerGenBean {
String fwdlname;
List<Servergean_bean_bean>list;
ServerGenBean(this.fwdlname,this.list);
factory ServerGenBean.fromJson(Map<String,dynamic> json)=>_$ServerGenBeanFromJson(json);
Map<String,dynamic> toJson()=>_$ServerGenBeanToJson(this);
}
@JsonSerializable()
class ServerPageBean {
double serverPackageAmount;
String serverpackagename;
List<SerpageBean_bean> list;
ServerPageBean(this.serverPackageAmount,this.serverpackagename,this.list);
// factory ServerPageBean.fromJson(Map<String,dynamic> json)=>_ServerPageBeanFromJson(json);
factory ServerPageBean.fromJson(Map<String,dynamic> json)=>_$ServerPageBeanFromJson(json);
Map<String,dynamic> toJson()=>_$ServerPageBeanToJson(this);
}
次次Bean 两个
@JsonSerializable()
class Servergean_bean_bean{
String fwxlid;
String fwxlname;
double price; //拿到数据是什么类型这里就定义什么样的类型
Servergean_bean_bean(this.fwxlid,this.fwxlname,this.price);
factory Servergean_bean_bean.fromJson(Map<String,dynamic> json)=>_$Servergean_bean_beanFromJson(json);
Map<String,dynamic> toJson()=>_$Servergean_bean_beanToJson(this);
}
@JsonSerializable()
class SerpageBean_bean {
String intid;
String serveritemname ;
SerpageBean_bean(this.intid,this.serveritemname);
factory SerpageBean_bean.fromJson(Map<String,dynamic> json)=>_$SerpageBean_beanFromJson(json);
Map<String,dynamic> toJson()=>_$SerpageBean_beanToJson(this);
}
书写完成后执行命令
flutter packages pub run build_runner build
这个时候会生成一个类名.g.dart的文件
最的要注意的时候
一般生成后不会报错，但如果我们的bean如果报错话 则需要修改一下 一般是这个两个地方会报错
会部没有报错后如何使用呢 ？
在代码里使用
打断点看映射到bean上的数据
至此我们就可以像 android开发一样 直接类名. 调用了 但唯一是没有set方法 因为有的需要我们需要填充假数据 去请求接口的，但这样的bean确实没有办法办到啊。
